Move uriSuffix extraction into lift_ajaxHandler.

By having it in doAjaxCycle, there were situations where the uri suffix
could get lost. The most obvious one was when a long-running ajax
request was occurring, and two AJAX requests were queued during that
time frame. This would result in the first request getting the second
request's uriSuffix, and the second request getting no suffix at all.

We now immediately put the uriSuffix into the sending data when
lift_ajaxHandler is called.
